Lanoree Brock's progenitor was a Human Je'daii Master of female gender. During the apex of the Infinite Empire's dominion, she functioned as an instructor at Bodhi, the Temple of Arts, for the Je'daii Order situated on Tython.
Having undergone training as a member of the Je'daii Order, she encountered her future husband while they were both Journeyers traversing the planet Tython during their Great Journey. Both young Je'daii found themselves drawn to Bodhi Temple, where the Force revealed their inherent artistic capabilities. A gifted musician specializing in both prose and poetry, she was well on her way to becoming a Je'daii of considerable reputation. Some years following the conclusion of their Journey, she and her husband became the parents of Lanoree and Dalien Brock. Residing in the Je'daii community surrounding the Temple of Arts, Brock dedicated her time to teaching at Bodhi, and in the evenings she would recite poetry to her children before they went to sleep. During their formative years, she imparted to her children the fundamentals of touching another's mind and the essential survival techniques needed to thrive on Tython.
During the war that erupted between Tython and Despot Queen Hadiya alongside her army, Brock spent a portion of his service on the planet Nox, a place where the conflict raged with particular intensity. In the aftermath of the war and the presumed demise of her son, Brock offered solace to her daughter at Dalien's memorial service, reassuring her that not all individuals successfully complete their Journey. Subsequently, she had infrequent contact with her daughter, who by the time of Dalien's reappearance during the Stargazer Uprising, had become a Je'daii Ranger. Following the Stargazer Uprising, Lanoree made her way back to Bodhi Temple and her parents' home for her brother's second Remembrance Ceremony, after she had ended his life in service to the Order.
Brock demonstrated herself to be a caring mother who displayed profound concern for her son. As her children prepared to embark on their Great Journey, she took her daughter aside and implored her to watch over Dalien, as she sensed his mediocre Force abilities. Becoming emotional as she expressed her fears that Dalien might be lured away from Tython, she firmly conveyed to her daughter that her worry was genuine and that her son's fascination with the distant past caused her unease.
